Question

Va rog foarte frumos sa imi rezolvati problema. T3=T2​

Answer 1

 

$\displaystyle\bf\\P_1=P_2\\2V_1=V_2\\2V_2=V_3\\\\Folosim~formula:~~~~~P\times V=constant~la~temperatura~constanta\\P_2\times V_2=P_3\times V_3\\\\2V_2=V_3\\P_2\times V_2=P_3\times 2V_2\\\\P_3=\frac{P_2\times V_2}{2V_2}\\\\P_3=\frac{P_2}{2}\\\\P_1=P_2\\\\\boxed{\bf~P_3=\frac{P_1}{2}}\\\\\boxed{\bf~P_3=\frac{3\cdot10^5}{2}~Pa}\\\\\boxed{\bf~P_3=1,\!5\cdot10^5~Pa}$
